| Abstract: | We study how individual inventors respond to incentives to work on 'clean' electricity technologies. Using natural gas price variation, we estimate output and entry elasticities of inventors and measure the medium-term impacts of a price increase mirroring the social cost of carbon. We find that the induced clean innovation response primarily comes from existing clean inventors. New inventors are less responsive on the margin than their average contribution to clean energy patenting would indicate. Our findings suggest a role for policy to increase the supply of clean inventors to help mitigate climate change. |

| Abstract: | We use micro-level data on fuel consumption, mileage, and travel mode to study plug-in hybrid drivers' response to fuel prices. When fuel prices rise, plug-in hybrids reduce fuel consumption more than gasoline and diesel cars. They do not reduce their mileage but increase electric recharging, without evidence of habit formation. As the share of kilometers driven in electric mode by plug-in hybrids is only half the official test cycle value, fuel prices are effective in improving the environmental performance of these vehicles. Considering the choice of fueling versus recharging, we estimate that drivers value time at €15 to €41/hour. |

| Abstract: | This paper lays out three sets of recommendations for the elected party, new members of the National Parliament and opposition parties. The upcoming elected government should create a fully functional parliament where the policy, plan, and acts can be presented and passed and discontinue discriminatory, non-competitive policies and set up a committee with specialists and climate-responsive people to prepare a roadmap for attaining the 40 per cent renewable energy target by 2041. |

| Abstract: | The market-based procurement of system services for network operators is gaining momentum in the current debate about the future market design in the energy sector. Since current sources of reactive power are primarily fossil-fuel power plants which will not be available in a carbon neutral energy system, reactive power will be sources from distributed assets in the electricity networks. The German regulator has proposed new rules for reactive power procurement, which are based on three pillars: The technical connection agreements, fully integrated network components owned by the network operators and market-based procurement. While this approach is primarily aiming at the reactive power demand on the transmission grid level, assets from the medium voltage grid can participate in this process as well. We evaluate this approach from an economic perspective and conclude that while such a three-pillar system can secure an effective provision of reactive power, the efficiency heavily depends on the regulatory system and that it provides the correct incentives for the network operator. |

| Abstract: | Este documento amplía la argumentación efectuada por Benavides, Cabrales y Delgado (2022), artículo que argumentó la importancia del gas natural y cuantificó los costos de desmontar el gas natural y el carbón de la generación eléctrica en Colombia entre 2023 y 2035. En esta ocasión se presentan cifras de orden de magnitud sobre densidad energética y los altos costos de la electricidad producida con fuentes no convencionales y baterías, para reforzar la necesidad de una transición a una velocidad que no lesione la economía del país; y se amplía el universo de cálculo de costos directos asociados a las restricciones en oferta de gas, incluyendo los principales sectores de consumo como el residencial, la generación térmica a gas y la industria (por fuera de coquería y refinación). La cuantificación utiliza la mejor información disponible en fuentes públicas.***** Abstract This document expands the argument made by Benavides, Cabrales and Delgado (2022), an article that argued the importance of natural gas and quantified the costs of removing natural gas and coal from electricity generation in Colombia between 2023 and 2035. It introduces figures on energy density and the high costs of electricity produced with non-conventional sources of energy and batteries are presented, to reinforce the need for a transition at a speed that does not harm the country's economy. In addition, it presents the direct costs associated with gas supply restrictions, including the main consumer sectors such as residential, gas-fired thermal generation and industry (apart from coking and refining). Quantification uses the best information available from public sources. |

| Abstract: | Electric vehicles (EVs) are likely to emerge as the main means of zero-emission road transport. China has used a variety of policy approaches to encourage EV adoption, including vehicle purchase subsidies. This study uses a three-dimensional dataset to estimate the effect of purchase subsidies for domestic EVs on adoption in 316 cities in China over January 2016–December 2019. An instrumental variable approach that utilizes the timing of the cancellation of local subsidies by the central government is pursued. The findings suggest that purchase subsidies for domestic EVs have led to a sizeable increase in uptake, but have discouraged uptake of imported EVs. Higher consumer awareness of the subsidies is associated with a larger proportional effect on uptake of domestically-produced vehicles. We estimate that increases in the per-vehicle subsidy rate have on average reduced carbon dioxide (CO2) emissions at a marginal subsidy cost of about 4, 453 CNY (US$712) per tonne, which is high. However, other benefits, including long-run benefits from the emergence of a new clean technology sector, may be substantial. |

| Abstract: | With more than 3 million new passenger cars sold every year, Germany's automobile industry is a major player on the European car market, and one seen as an important arena for achieving climate protection targets. Using high-resolution car registration data from each state in Germany between January 2015 to March 2020, we estimate reduced-form panel data models to identify the effects of three flagship policies aimed at reducing transport emissions from cars: diesel bans, rebates for battery vehicles, and subsidies for charging station projects. The models show that the policies have significant effects on the sales of specific powertrains. But policy simulations that incorporate estimates of lifecycle CO2-emissions reveal that they have only negligible effects on emission reductions and are costly. Rebates on the purchase of a battery-electric or plug-in hybrids result in a cost per ton of reduced CO2-emissions of over €1000. Even the most optimistic scenarios result in a cost per ton of CO2-reduced by subsidies for the construction of charging stations of at least €400. These figures are very large when compared with the cost of abatement implicit in the price of allowances on the European Emissions Trading System, with important implications on cross-sectoral trading, such as that envisioned in the European Union's Fit-for-55 program. |
| Abstract: | Mit mehr als 3 Millionen verkauften Neuwagen pro Jahr ist die deutsche Automobilindustrie ein wichtiger Akteur auf dem europäischen Automobilmarkt und gilt als wichtiger Schauplatz für die Erreichung der Klimaschutzziele. Unter Verwendung von detaillierten Kfz-Zulassungsdaten aus allen deutschen Bundesländern für den Zeitraum von Januar 2015 bis März 2020 schätzen wir reduzierte Paneldatenmodelle, um die Auswirkungen dreier politischer Maßnahmen zu ermitteln, die auf die Reduzierung der verkehrsbedingten Emissionen von Pkw abzielen: Dieselfahrverbote, Rabatte für Batteriefahrzeuge und Subventionen für Ladestationen. Die Modelle zeigen, dass diese Maßnahmen erhebliche Auswirkungen auf den Absatz bestimmter Antriebsarten haben. Simulationen, die Schätzungen der CO2-Emissionen über den gesamten Lebenszyklus einbeziehen, zeigen jedoch, dass diese Maßnahmen nur vernachlässigbare Auswirkungen auf die Emissionsreduzierung haben und kostspielig sind. Rabatte für den Kauf eines batterieelektrischen Fahrzeugs oder eines Plug-in-Hybridfahrzeugs führen zu Kosten pro Tonne reduzierter CO2-Emissionen von über 1000 €. Selbst die optimistischsten Szenarien führen zu Kosten pro Tonne CO2, die durch Subventionen für den Bau von Ladestationen reduziert werden, von mindestens 400 €. Diese Zahlen sind sehr hoch, wenn man sie mit den Vermeidungskosten vergleicht, die im Preis der Zertifikate im Europäischen Emissionshandelssystem enthalten sind, was erhebliche Auswirkungen auf den sektorübergreifenden Handel hat, wie er im Fit-for-55-Programm der Europäischen Union vorgesehen ist. |

| Abstract: | This paper investigates the impact of oil price variations on sectoral inflation for a sample of 10 top oil importing and exporting countries. Specifically, we analyze the effects of oil prices on the consumer price index using monthly data spanning the July 2009 to February 2021 period. Two nonlinear techniques are used to this end: The nonlinear autoregressive distributed lag approach (NARDL), and the Hansen's model (2000). Our econometric results first indicate that the effect of oil price on inflation tends to change across sectors and countries. Second, the inflationary effects of variations in oil prices are likely to affect the energy sector, such as transport and equipment, which are the most dependent on oil. Third, the effect of oil price exists for all countries, but it is stronger in oil-importing than in oil-exporting ones. Besides, the country most sensitive to the oil price level is China. |

| Abstract: | This paper examines the determinants of residential CO 2 emissions, which are not covered by the European Union Emissions Trading System (EU ETS), in 19 European countries between 2000-2017. Using both static and dynamic panel models, we found strong relationships between CO 2 emissions per capita, GDP per capita, energy prices and heating needs. We then assessed the impact of European carbon taxation and show that a e20/tonne CO 2 tax lowers emissions by 1% on average. We found that this tax affects countries differently in terms of tax revenue-to-GDP ratio. Poland and the Czech Republic would have to pay the highest contribution, and Portugal and Denmark the lowest. Finally, we propose a scenario that equalizes countries' tax burdens. We show that, were Europe to redistribute all tax revenues, the main beneficiaries would be Poland and Belgium, while Denmark and Luxembourg would have to pay a surtax. |

| Abstract: | In this paper, we use scenario analysis to assess the macroeconomic effects of carbon transition policies aimed at mitigating climate change. To this end, we employ a version of the ECB’s New Area-Wide Model (NAWM) augmented with a framework of disaggregated energy production and use, which distinguishes between “dirty” and “clean” energy. Our central transition scenario is that of a permanent increase in carbon taxes, which are levied as a surcharge on the price of dirty energy. Our findings suggest that increasing euro area carbon taxes to an interim target level consistent with the transition to a net-zero economy entails a transitory rise in inflation and a lasting, albeit moderate decline in GDP. We show that the short and medium-term effects depend on the monetary policy reaction, the path of the carbon tax increase and its credibility, while expanding clean energy supply is key for containing the decline in GDP. Undesirable distributional effects can be addressed by redistributing the fiscal revenues from the carbon tax increase across households. |

| Abstract: | The social cost of carbon (SCC) serves as a concise gauge of climate change's economic impact, often reported at the global and country level. SCC values are disproportionately high for less-developed, populous countries. Assessing the contributions of urban and non-urban areas to the SCC can provide additional insights for climate policy. Cities are essential for defining global emissions, influencing warming levels and associated damages. High exposure and concurrent socioenvironmental problems exacerbate climate change risks in cities. Using a spatially explicit integrated assessment model, the SCC is estimated at USD$137-USD$579/tCO2, rising to USD$262-USD$1, 075/tCO2 when including urban heat island (UHI) warming. Urban SCC dominates, with both urban exposure and the UHI contributing significantly. A permanent 1% reduction of the UHI in urban areas yields net present benefits of USD$484-USD$1, 562 per urban dweller. Global cities have significant leverage and incentives for a swift transition to a low-carbon economy, and for reducing local warming. |

| Abstract: | Company carbon disclosures are crucial in assessing a firm's impact on the environment, and many policy actions are associated with this information. As a response to the increasing demand for transparency, many firms disclose carbon emissions through sustainability reports and voluntarily engage with external assurance of the reported information. However, the possible existence of systematic differences in reported emissions with respect to their assurance status is still under-explored. This study investigates the causal effect of third-party assurance on carbon disclosures in a sample of European companies. Findings suggest that non-assuring firms may be under-reporting their direct GHG emissions by up to a magnitude comparable to the largest annual reduction of EU emissions in history. On the contrary, the effect of assurance is much weaker to almost absent in indirect, Scope 2, emissions possibly due to their clear and easily verifiable estimation nature. The findings demonstrate that third-party assurance can provide more reliable and certainly more prudent estimates of corporate GHG emissions which are relevant to corporate sustainability strategy, policymaking and, ultimately, climate change mitigation. |

| Abstract: | Despite the ambitious carbon reduction targets set by policy makers worldwide, current investments fall well short of the net-zero emissions scenario. This paper analyses the factors holding back corporate green investment, with a particular focus on the role of firm capacity – specifically financing constraints and weak green management practices – and its interaction with environmental policy. Combining a variety of econometric techniques, including panel data models, difference-in-differences settings and instrumental variable approaches, our cross-country analysis on large listed companies shows that: i) both financing constraints and a lack of green managerial capacity reduce firms’ probability of investing in green technologies, leading to higher emission intensity; ii) well-designed environmental policies can mitigate these impacts. A case study using more granular data on Portuguese firms further shows that: iii) green investment is more elastic to financing conditions than other types of investment; iv) investment in integrated technologies is more sensitive to financing conditions and to managerial capacity compared to end-of-pipe solutions. Lastly, the paper discusses a wide range of policy options that may be considered to foster the green transition through upgrading firms’ capacity. |

| Abstract: | The global shift toward sustainability and increased digitalization is evident. Nations are integrating renewable energy, carbon emission reduction, and advancements in green technologies into their development plans. Simultaneously, Industry 4.0 has revealed the diverse ways technology influences human life. Rather than separate factors, these dual forces are interconnected elements that countries must navigate for sustainable progress. As countries pursue development strategies, taking a closer look at this twin phenomenon is important. This study assesses how investments, labor, science, technology, innovation, and artificial intelligence contribute to this dual transformation. Through desk reviews and synthesized data, this paper highlights relevant initiatives, technology-related risks, and recommendations for addressing existing gaps. The study acknowledges existing government initiatives aligned with green transition and digitalization. However, it identifies persistent issues, such as inadequate investment in clean climate technologies, shortage of skilled workers in green sectors, and uncertainties regarding the sustainability of AI. To overcome these challenges, the paper proposes directions to bridge gaps, remove barriers to participation, and enhance capabilities, aiming to harness this combined transition's potential fully.

| Abstract: | This paper investigates the design of a recent regulatory proposal aimed at favoring the emergence of a battery recycling industry in Europe. Electric mobility is deemed necessary to cut CO2 emissions in the transport sector but the industrial and environmental impacts of lithium-ion battery manufacturing are controversial. A recent regulatory proposal from the European Commission introduces the obligation to attain a series of minimum thresholds of recycled materials for the new batteries to be manufactured after 2030. This paper discusses the conditions required for that obligation to be fulfilled. It develops a material flow model that projects battery wastes and their recycling potential. Our findings indicate that the feasibility of proposed thresholds is not very sensitive to changes of material intensities from battery technology shifts, recycling efficiencies, or the faster uptake of demand. On the contrary, battery lifetimes are the most crucial parameters for recycling potential. We believe that this result could jeopardize avenues for extending battery lifetimes such as second-battery usage. Our policy recommendations are twofold. First, we recommend lower thresholds to improve the regulation credibility. Second, the regulation should integrate other objectives that address the lifetime of batteries. |

| Abstract: | While natural resources significantly contribute to global socio-economic development, the unresolved question of their volatility's role in decoupling economic growth and carbon emissions persists. Previous empirical studies have underscored both positive and negative impacts of natural resource exploration on economic growth and the environment. This study addresses the knowledge gap by employing a linear non-linear panel ARDL framework to investigate the correlation between natural re source volatility and sustainable development in the BRICS economies. Our key findings reveal that natural resource volatility adversely impacts green growth within the linear model in both the short and long run. Conversely, in the non-linear model, an increase in natural resource volatility negatively influences green growth, whereas a decrease encourages green growth, albeit only in the long run. Moreover, we found that technological development, stringent environmental policies, and trade openness are conducive to green growth. These results underscore the necessity for managing natural resource volatility to foster sustainable development, particularly in emerging BRICS economies. |

| Abstract: | Carbon abatement decisions are usually based on the implausible assumption of constant social preference. This paper focuses on a specific case of market and non-market goods, and investigates the optimal climate policy when social preference for them is also changed by climate policy in the DICE model. The relative price of non-market goods grows over time due to increases in both relative scarcity and appreciation of it. Therefore, climbing relative price brings upward the social cost of carbon denominated in terms of market goods. Because abatement decision affects the valuation of non-market goods in the utility function, unlike previous climate-economy models, we solve the model iteratively by taking the obtained abatement rates from the last run as inputs in the current run. The results in baseline calibration advocate a more stringent climate policy, where endogenous social preference to climate policy raises the social cost of carbon further by roughly 12%-18% this century. Moreover, neglecting changing social preference leads to an underestimate of non-market goods damages by 15%. Our results support that climate policy is self-reinforced if it favors more expensive consumption type. |

| Abstract: | This paper studies international trade in equipment used in the combustion of fossil fuels. Informed by a theoretical analysis, we identify a type of technology leakage hitherto unexplored in the literature: a country’s export of combustion equipment tends to increase, all else equal, in the stringency of its climate policy. We test this prediction by estimating the impact of carbon pricing on international trade in combustion equipment using detailed data on bilateral trade and domestic carbon prices for the period 1995–2021. Our estimates reveal a robust positive association between the stringency of climate policies and exports of combustion equipment, providing clear evidence for the existence of technology leakage. We argue that standard policies to mitigate carbon leakage are unlikely to prevent technology leakage, raising novel policy questions. |

| Abstract: | In a world increasingly threatened by climate change and its associated risks, there's an urgent need to actively seek solutions for environmental protection and sustainable economic development. Central to this effort is understanding the role of environmental taxes and productive capacities in shaping environmental outcomes. Focusing on countries within the European Economic Area (EEA), this research uses advanced second-generation econometric techniques to examine this relationship. The use of cross-sectional autoregressive distributive lag (CS-ARDL) and dynamic common correlated effects (DCCE) models allows for a robust examination of panel data and provides reliable results. The results reveal an inverted U-shaped relationship, or Environmental Kuznets Curve (EKC), between GDP growth and environmental degradation in the EEA economies. Furthermore, while our data reveal a significant negative correlation between environmental taxes and CO2 emissions, we find that productive capacities have a more significant impact on reducing these emissions. These findings call for further research into the effectiveness of policies to support productive capacities in achieving environmental protection goals in the EEA. |

| Abstract: | The main argument in favor of markets in environmental contexts is the same as in other contexts: their ability to promote efficient allocations and production. But environmental problems bring their own challenges: their underlying bio-physical processes - and the technologies to monitor them - constrain what is feasible or even desirable. This chapter illustrates the main design dimensions in environmental markets, the trade-offs involved and their impact on performance, through the lens of a regulated market for pollution rights (the EU emissions trading scheme) and a voluntary market for the provision of environmental services (the global market for carbon credits). While both markets eventually contribute to climate change mitigation, their organisation as a “pollution market”, for the former, and as a “provision market”, for second, means that different design considerations take precedence. Both markets also face challenges: volatile prices in the EU emissions scheme and low trust for voluntary carbon markets. We discuss how alternative design options could address those.Keywords: Natural |

| Abstract: | Energy security is a comprehensive concept, and pursuing it as a developmental goal entails, first and foremost, a clearer understanding of what it means. This study proposes six broad elements in assessing energy security: sufficiency, reliability, resilience, affordability, accessibility, and sustainability. In assessing the energy security situation in the Philippines, the study employs an indicators-based assessment. Based on existing literature, the method involves defining specific energy security indicators (ESIs) corresponding to the six broad elements mentioned, running some calculations, and conducting trend analysis using available data. The analyses of ESI trends over time and comparisons with other Southeast Asian countries reveal notable findings, most of which point to the current energy insecurity of the Philippines. The study then offers recommendations to improve energy security in the country and suggests that each element of energy security be considered an area of future research. As a demonstration of further scrutiny of an aspect of energy security, the study further examines energy sufficiency by forecasting electric power demand and comparing the forecasts with the government’s outlook on generating capacity up to 2028. The results highlight the necessity of timely investments in additional generating capacity and an efficient government permitting system.

| Abstract: | Overhead electrical power lines and pylons have long raised concerns regarding the effects of electromagnetic fields on health, noise pollution and the visual impact on rural landscapes. These issues are once again salient because of the need for new lines to connect sources of renewable energy to the grid. In this study we provide new evidence on the cost implied by these externalities, as revealed in house prices. We use a spatial difference-in-difference approach that compares price changes in neighbourhoods that are close to overhead power lines, before and after they are constructed, with price changes in comparable neighbourhoods further away. Our findings suggest that the construction of new overhead pylons reduces prices by 3.6% for properties up to 1200 meters away, suggesting the impacts extend further than previously estimated. |

| Abstract: | Changes in energy prices are generally likely to have implications for the competitiveness of economies. Besides, a more profound concern is the disparity in the availability and price of energy might erode the productive efficiency in industrial units of some regions, eventually leading to deindustrialization. |

| Abstract: | In the era of sustainability, firms grapple with the decision of how much to invest in green innovation and how it influences their economic trajectory. This study employs the Crepon, Duguet, and Mairesse (CDM) framework to examine the conversion of R&D funds into patents and their impact on productivity, effectively addressing endogeneity by utilizing predicted dependent variables at each stage to exclude unobservable factors. Extending the classical CDM model, this study contrasts green and non-green innovations' economic effects. The results show non-green patents predominantly drive productivity gains, while green patents have a limited impact in non-heavy polluting firms. However, in high-pollution and manufacturing sectors, both innovation types equally enhance productivity. Using unconditional quantile regression, I found green innovation's productivity impact follows an inverse U-shape, unlike the U-shaped pattern of non-green innovation. Significantly, in the 50th to 80th productivity percentiles of manufacturing and high-pollution firms, green innovation not only contributes to environmental sustainability but also outperforms nongreen innovation economically. |

| Abstract: | Innovation policy faces a tradeoff between growth and climate objectives when the knowledge spillover externality from clean innovation is low compared to other sectors. To make such a comparison, we use patent data to estimate field-specific spillover returns generated by R&D support. Supporting Clean presents itself as a win-win opportunity, yielding global returns one-eighth higher than those of an untargeted policy. Nevertheless, only a modest portion of the returns stays within country borders, raising the question of whether national interests distort efficient allocation. Our policy simulations underscore the benefits of supranational coordination in clean innovation policy, potentially boosting returns by approximately 25% for the EU and over 60% globally. Moreover, the EU benefits strongly from US Clean innovation spillovers, impacting the debate on the Inflation Reduction Act. Overall, we identify no explicit innovation policy tradeoff in tackling the twin challenges of economic growth and climate change but emphasize the necessity for international cooperation. |

| Abstract: | The study of energy and climate has become of primary relevance for policymakers in central banks and other institutions. Current analyses for Chile suggest medium to strong direct physical effects, with some studies pointing to relatively higher impacts in the northern and central regions. Also, indirect effects, such as those originating from green transitions around the world, are likely to be significant. This paper provides a brief review of the effects that climate change may have on the economy and describes efforts made by the Central Bank of Chile to gain a better understanding of these effects. These efforts include: geo-referencing of assets and the primary physical risks they face, characterization of the transmission channels through which climate risks can propagate, a better estimation of the uncertainty of climatic events and the development of new general equilibrium models. |

| Abstract: | The surge in economic and human development has led to increasing concerns about environmental degradation, thus necessitating effective strategies to enhance sustainability and environmental quality. Therefore, this study empirically examines the impact of environmental fiscal policies, environmental technologies, and research and development (R&D) expenditures on achieving environmental sustainability in the G7 countries. Using advanced econometric techniques, including the Cross-Sectionally Augmented Autoregressive Distributed Lags (CS-ARDL) model and the Dynamic Common Correlated Effects (DCCE) approach, the study identifies both short-run and long-run correlations between the aforementioned variables and their impact on greenhouse gas (GHG) emissions. Our findings confirm the inverted U-shaped Kuznets Curve relationship and reinforce the previous literature on the complex dynamics between economic growth and GHG emissions specific to developed countries. The research also supports the effectiveness of well-designed environmental taxes in reducing environmental degradation and GHG emissions, consistent with and extending existing studies in this area. In addition, the study provides empirical evidence of the critical role of environmental technologies and targeted R&D expenditures in improving environmental quality. In terms of policy implications, our research underscores the urgency for policymakers in the G7 countries to fine-tune environmental taxation mechanisms and increase investment in sustainable technological solutions. Specific recommendations include the development of more efficient tax systems that adhere to the polluter-pays principle, as well as financial incentives such as tax credits and subsidies aimed at accelerating green technology adoption and innovation. In doing so, the study seeks to contribute to the broader discourse on environmental policy and sustainable development, providing valuable perspectives for both the academic community and policy actors |

| Abstract: | In 2017, Côte d'Ivoire imposed restrictions on the imports of used vehicles into its territory, one of which aims is environmental protection. This paper focuses on this policy and investigates its impacts on both (i) vehicle smuggling and (ii) environmental protection in the country. As finding a credible control for Côte d'Ivoire in the aim of the evaluation is thus challenging, the Augmented Synthetic Control Method is implemented to construct a valid counterfactual for the country's path without the law, with WAEMU member countries as control states. This method is used with an outcome model in a Panel Fixed Effects simulation and covariates configuration, to assess the Average Treatment effect on the Treated (ATT) on the outcome of interest after the passage of the 2017 law. The use of a panel structure allows for controlling time-invariant omitted variables correlated with the law adoption. The assessment shows that the policy has led to an increase of almost 39% in the per capita vehicle smuggling in the country. Furthermore, the policy has induced a reduction in the per capita CO2 emissions in the country with an average treatment effect indicating a decrease of -0.051 metric tons per inhabitant. These effects do not vanish over time and results remain robust to different robustness and falsification placebo tests. |

| Abstract: | Nach dem am 1. Februar 2023 in Kraft getretenen Windenergieflächenbedarfsgesetz (WindBG) müssen bis 2032 2% der Fläche Deutschlands für die Produktion von Windenergie bereitgestellt werden. Das Gesetz legt dabei Flächenbeitragswerte für die Länder fest, die in den Flächenländern zwischen 1, 8% und 2, 2% der jeweiligen Landesfläche liegen. Auch wenn die weitgehenden Änderungen des Planungsrechts im Sinne der Energiewende zu begrüßen sind, stellt die Implementierung des 2-%-Flächenziels bei der Windenergie für die Planungsträger eine große Herausforderung dar. In den 12 Ländern, in denen es die Ebene der Regionalplanung gibt, wurde diese mit der Umsetzung beauftragt. Sie muss in den meisten Planungsregionen deutlich mehr Flächen als bisher ausweisen. Dabei ist sie auf die Zuarbeit anderer Institutionen angewiesen, um rechtssicher planen zu können. Wo die Flächenziele nicht erreicht werden, drohen rechtliche Sanktionen. Das vorliegende Positionspapier stellt auf Basis der Diskussionen im Ad-hoc-Arbeitskreis "Windenergie an Land" der ARL zentrale Thesen vor, die jeweils argumentativ unterlegt die Umsetzung des "2%- Zieles" und die Optimierung des Planungsprozesses unterstützen sollen. |
| Abstract: | According to the "Windenergieflächenbedarfsgesetz" (WindBG), which came into force on February 1, 2023, 2% of Germany's territory must be made available for production of wind energy by 2032. The law sets out area contribution values for the federal states, which are between 1.8% and 2.2% of the respective state's area. The fundamental changes to planning law are certainly to be commended in the interests of the energy transition. However, the implementation of the 2% area target for wind energy is a great challenge for the planning authorities. In the 12 federal states where a regional planning level is established, regional planning has to implement the goals. In most planning regions, significantly more areas need to be designated than in the past. To be able to plan with confidence, the planning authorities are reliant on the input of other institutions. Where the area targets are not met, there is a threat of legal sanctions. This position paper presents central theses based on the discussions in the ARL ad hoc working group "Windenergie an Land", which are aimed at supporting the implementation of the "2% target" and the optimization of the planning process by providing arguments. |

| Abstract: | While wind power is considered key in the transition towards net zero, there are concerns about adverse health impacts on nearby residents. Based on precise geographical coordinates, we link a representative longitudinal household panel to all wind turbines in Germany and exploit their staggered rollout over two decades for identification. We do not find evidence of negative effects on general, mental, or physical health in the 12-Item Short Form Survey (SF-12), nor on self-assessed health or doctor visits. We also do not find evidence for effects on suicides, an extreme measure of negative mental health outcomes, at the county level. |

| Abstract: | For a large majority of economists, the carbon tax, legitimized by its theoretical foundations, should be at the heart of policies to combat climate change. However, as environmental economist Jean-Charles Hourcade already noted in 2015, "the transition from theory to practice is a difficult exercise when it comes to carbon taxes". We will first see why and how well-being economics came to consider efficiency as the sole criterion and how the carbon tax became a flagship measure for environmental economists. We will then see the difficulties they encounter when they try to reconcile the fundamentals with the demands of social and political realities at the time of implementing the measure. Finally, we will see how normative approaches which may have seemed relegated to the second rank of the discipline, mobilize these events to show the insufficiency of the criterion of effectiveness and the need to take into account ethical criteria in the choice of public policy instruments. . |
| Abstract: | Pour une grande majorité des économistes, la taxe carbone, légitimée par ses fondements théoriques, devait se situer au coeur des politiques de lutte contre le changement climatique. Cependant, comme le notait déjà en 2015 l'économiste de l'environnement Jean-Charles Hourcade, « le passage de la théorie à la pratique est un exercice difficile en matière de taxe carbone ». Nous verrons dans un premier temps pourquoi et comment l'économie du bien-être en est venue à considérer l'efficacité comme unique critère et comment la taxe carbone est devenue une mesure phare pour les économistes de l'environnement. Nous verrons ensuite les difficultés que ceux-ci rencontrent lorsqu'ils essaient de concilier les fondamentaux aux exigences des réalités sociales et politiques au moment de la mise en place de la mesure. Enfin, nous verrons comment des approches normatives qui avaient pu sembler reléguées au second rang de la discipline, mobilisent ces évènements pour montrer l'insuffisance du critère d'efficacité et la nécessité de tenir compte de critères éthiques dans le choix des instruments des politiques publiques. |

| Abstract: | Mindfulness practices have the potential to induce the cognitive and behavioral changes needed to foster pro-environmental behavior and increase support toward sustainable and climate-oriented policies. However, the empirical evidence of the effectiveness of meditation on sustainable behavior is limited and mostly confined to correlational studies, often based on the same type of mindfulness interventions. In this paper, we report the results of an online experiment (n = 1000) comparing the impact of three different short-term mindfulness interventions on various (self-reported and incentivized) measures of mindfulness state and sustainable behavior. While only one of our interventions is found to impact environmental attitude and climate policy support directly, we show that the three meditation practices indirectly foster sustainable behavior through preidentified mediators. These results are relevant for organizations and policymakers who seek to foster climate policy support and environmental attitudes in their stakeholders. |

| Abstract: | Bioethanol is promoted as a means of tackling climate change, diversifying energy sources and securing energy supply. However, there also concerns that their wider deployment could lead to unintended environmental consequences. Life cycle assessment (LCA) is a widely used methodology to assess the environmental performance of biofuels. However, its outcomes strongly depend on the inventory data and modeling assumptions. Agronomic variables such as crop yields, nitrogen fertilizer rates or field emissions of nitrous oxide are very sensitive inputs, as are soil carbon dynamics in response to land use changes (LUC) entailed by the deployment of energy crops. Models simulating agroecosystem processes and the economics of agricultural farms are promising tools to predict such variables and improve the reliability of LCA. Here, we combined the agro-ecosystem model CERES-EGC, the farm economic model AROPAj and the LCA approach to investigate the effect of local drivers on the environmental impacts of bioethanol from miscanthus and switchgrass over France. Overall, lignocellulosic bioethanol achieved GHG abatement targets in the 74 %–94 % range compared to gasoline, and complied with the 50 % minimum imposed by European regulations. Miscanthus-based ethanol achieved up to twice lower environmental impacts than switchgrass due to 50 % higher biomass yields overall. Low fertilizer N input rates (in the 0-30 kg N ha-1 yr-1 range) proved the most efficient strategy to optimize energy return. Significant inter-regional variability occurred, especially in terms of soil C sequestration rates, which weighed in substantially on GHG budgets. Some regions were more efficient than others as a result, which advocates a site-specific approach and a potential prioritization when planning biorefineries, taking into account local production and environmental performance potentials. Compared to previous studies, ours provided high-resolution data in terms of crop yields, nitrous oxide emissions and soil C dynamics, factoring in LUC effects at local to regional scales. |
| Abstract: | Le bioéthanol est présenté comme un moyen de lutter contre le changement climatique, de diversifier les sources d'énergie et de garantir l'approvisionnement énergétique. Toutefois, on craint que son déploiement à plus grande échelle n'entraîne des conséquences environnementales imprévues. L'analyse du cycle de vie (ACV) est une méthodologie largement utilisée pour évaluer les performances environnementales des biocarburants. Toutefois, ses résultats dépendent fortement des données d'inventaire et des hypothèses de modélisation. Les variables agronomiques telles que le rendement des cultures, les taux d'engrais azotés ou les émissions d'oxyde nitreux dans les champs sont des données très sensibles, tout comme la dynamique du carbone du sol en réponse aux changements d'utilisation des sols entraînés par le déploiement des cultures énergétiques. Les modèles simulant les processus agroécosystémiques et l'économie des exploitations agricoles sont des outils prometteurs pour prédire ces variables et améliorer la fiabilité de l'ACV. Ici, nous avons combiné le modèle agro-écosystémique CERES-EGC, le modèle économique agricole AROPAj et l'approche ACV pour étudier l'effet des facteurs locaux sur les impacts environnementaux du bioéthanol produit à partir de miscanthus et de switchgrass en France. Dans l'ensemble, le bioéthanol lignocellulosique a atteint des objectifs de réduction des GES de l'ordre de 74 à 94 % par rapport à l'essence, et a respecté le minimum de 50 % imposé par les réglementations européennes. L'éthanol à base de miscanthus a eu jusqu'à deux fois moins d'impact sur l'environnement que le panic érigé, grâce à des rendements en biomasse globalement supérieurs de 50 %. Les faibles taux d'apport d'engrais N (de l'ordre de 0 à 30 kg N ha-1 an-1) se sont révélés être la stratégie la plus efficace pour optimiser le rendement énergétique. Une importante variabilité interrégionale a été observée, notamment en ce qui concerne les taux de piégeage du carbone dans le sol, ce qui a eu un impact considérable sur les bilans de GES. Certaines régions étaient donc plus efficaces que d'autres, ce qui plaide en faveur d'une approche spécifique au site et d'une priorisation potentielle lors de la planification des bioraffineries, en tenant compte des potentiels locaux de production et de performance environnementale. Par rapport aux études précédentes, la nôtre a fourni des données à haute résolution en termes de rendement des cultures, d'émissions d'oxyde nitreux et de dynamique du carbone dans le sol, en tenant compte des effets de l'utilisation durable de l'espace à l'échelle locale et régionale. |

| Abstract: | A systematic review of green consumer behaviors in five prominent consumer research journals revealed that behaviors with greater potential for climate mitigation (e.g., plant-based consumption) have not been broadly studied, indicating promising opportunities for future research. In an exploratory survey, we conceptually replicate this finding using a sample of consumer researchers with a general interest in studying higher-potential behaviors. We consider evidence for potential explanations, such as researchers’ primary focus on construct-to-construct mapping, a tendency to study behaviors that researchers have personal experience with or are easy to implement, a lack of incentives to study higher-potential behaviors, and insufficient knowledge of mitigation potential. To help shift consumer researchers’ focus on higher-potential behaviors, we offer concrete recommendations, such as proactively considering mitigation potential both as authors and reviewers, and utilizing phenomenon-to-construct mapping for enhancing theoretical contributions. In sum, we hope that this research will help interested consumer researchers to provide more relevant answers to the urgent challenge of climate change mitigation. |

| Abstract: | This paper uses administrative tax records linked to Census demographic data and high-resolution measures of fine small particulate (PM2.5) exposure to study the evolution of the Black-White pollution exposure gap over the past 40 years. In doing so, we focus on the various ways in which income may have contributed to these changes using a statistical decomposition. We decompose the overall change in the Black-White PM2.5 exposure gap into (1) components that stem from rank-preserving compression in the overall pollution distribution and (2) changes that stem from a reordering of Black and White households within the pollution distribution. We find a significant narrowing of the Black-White PM2.5 exposure gap over this time period that is overwhelmingly driven by rank-preserving changes rather than positional changes. However, the relative positions of Black and White households at the upper end of the pollution distribution have meaningfully shifted in the most recent years. |

| Abstract: | The European Union (EU) finds itself in a critical need for rare earths, particularly the refined products essential for the production of electric cars, turbines, and other technological applications. However, the refining process is not only energy-intensive but also poses significant environmental risks. Consequently, local communities, as evidenced by instances in Spain and Portugal, vehemently oppose having such operations in their vicinity, advocating a "beggar thy neighbour" policy. The EU currently relies heavily on China, which controls the majority of global processing, commanding 90% of all rare earths and 60% of lithium. In response to these challenges, the EU took a crucial step in November 2023 by reaching a preliminary agreement on the European Critical Raw Materials Act (CRMA). This legislative initiative aims to enhance and diversify the EU's supply of critical raw materials (CRM), foster the circular economy, fortify Europe's strategic autonomy, and explore alternatives to mitigate dependence. Recent transnational crises, including disruptions to supply chains during the COVID-19 pandemic and Russia's invasion of Ukraine, underscore the imperative of secure supply chains across all economic sectors. These crises also underscore the significant influence wielded by major emerging economies, notably the BRICS countries (Brazil, Russia, India, China, and South Africa), which dominate key global supply chains, including those for critical raw materials (CRMs). Russia plays a pivotal role as one of the world's largest suppliers of palladium (40% of global supply), the second-largest supplier of platinum (13%) and nickel (12%), and a substantial contributor of aluminium and copper. Furthermore, Russia possesses the potential to emerge as a major player in the rare earths market due to its extensive reserves. The country also accounts for a considerable share of the EU's acquisitions, including palladium (41%), platinum (16%), cobalt (5%), and lithium (4%). Notably, Russia serves as the primary EU source for platinum group metals processing (iridium, platinum, rhodium, ruthenium; 40%), phosphate rock extraction (20%), lithium processing (4%), and scandium processing (1%). To attain greater independence in external CRM provision, the EU must make significant investments in its mining and processing facilities. However, mining represents merely the initial phase; subsequent steps involve the separation of rare earth elements (REE) from oxides, refining, and alloy forging a complex, highly specialized, multi-stage process. In this regard, relative newcomers like Europe lag behind, as China has solidified its dominant position in each phase through a concerted, long-term industrial strategy supported by state subsidies. |

| Abstract: | Strong policies with sustainable incentives are needed to accelerate the EV transition. This paper assesses various feebate designs assessing recent policy evolution in five European countries. While there are key design elements that should be considered, there is no optimal feebate design. Different policy objectives could be served by feebates influencing its design and effectiveness. Using feebates to transition to EVs has emerged a key objective. With the financial sustainability of EV incentive programs being questioned, a self financing market mechanism could be the need of the hour solution. Irrespective of the policy goals, a feebate will impact both the supply side, i.e., the automotive industry and the consumer side. Globally, feebates can be used to effect technology leapfrogging while navigating the political economy of clean transportation policy in different country contexts. This paper highlights thirteen design elements of an effective feebate policy that can serve as a foundation for policymakers. |

| Abstract: | Currently, wind energy is one of the most important sources of renewable energy. Offshore locations for wind turbines are increasingly exploited because of their numerous advantages. However, offshore wind farms require high investment in maintenance service. Due to its complexity and special requirements, maintenance service is usually outsourced by wind farm owners. In this paper, we propose a novel approach to determine, quantify, and reduce the possible conflicts of interest between owners and maintenance suppliers. We created a complete techno-economic model to address this problem from an impartial point of view. An iterative process was developed to obtain statistical results that can help stakeholders negotiate the terms of the contract, in which the availability of the wind farm is the reference parameter by which to determine penalisations and incentives. Moreover, a multi-objective programming problem was addressed that maximises the profits of both parties without losing the alignment of their interests. The main scientific contribution of this paper is the maintenance analysis of offshore wind farms from two perspectives: that of the owner and the maintenance supplier. This analysis evaluates the conflicts of interest of both parties. In addition, we demonstrate that proper adjustment of some parameters, such as penalisation, incentives, and resources, and adequate control of availability can help reduce this conflict of interests. |

| Abstract: | Multiple challenges have emerged over the last decades, threatening human, socio-economic and environmental systems. Climate change impacts, degradation of limited natural resources, unsustainable demand, production and consumption practices, diseases, crises in the energy, food and biodiversity sectors, economic recessions, and many more, interconnected dynamic threats, require coordinated and efficient solutions. Under the UN's Sustainable Development Solutions Network (SDSN) we developed the Global Climate Hub (GCH), an international initiative for tackling such challenges. After 12 years of SDSN's action, we present the structure and ways of operation of the GCH, along with the principles that allow it to successfully bridge holistic scientific approaches with the society, for implementing fair and publicly acceptable sustainable pathways. The GCH's five innovations are analyzed, namely, the use of integrated 'cutting-edge models', with the support of 'digital AI-driven data-handling infrastructure', for the development of case-specific 'socio-economic narratives' and 'stakeholder engagement' for co-designing solutions. Moreover, the nine units of the GCH are scrutinized in terms of scope, methods, and tools. These cover a wide range of expertise in digital applications, climate science, energy, transport, land, water, food, biodiversity, and marine systems, public health, solutions' application, policy, finance, labour markets, participatory approaches, education and training. This contribution provides a complete picture of a global, developing - and successful so far - vision for a climate-neutral, resilient and sustainable world. |

| Abstract: | We quantify intraday volatility connectedness between oil and key financial assets and assess how it is related to uncertainty and sentiment measures. For that purpose, we integrate the well-known spillover methodology with a TVP VAR model estimated on a unique, vast dataset of roughly 300 thousand 5 minute quotations for crude oil, the US dollar, S&P 500 index, gold and US treasury prices. This distinguishes our investigation from previous studies, which usually employ relatively short samples of daily or weekly data and focus on connectedness between two asset classes. We contribute to the literature across three margins. First, we document that market connectedness at intraday frequency presents new picture on markets co-movement compared to the estimates obtained using daily data. Second, we show that at 5 minute frequency volatility is mostly transmitted from the stock market and absorbed by the bond and dollar markets, with oil and gold markets being occasionally important for volatility transmission. Third, we present evidence that daily averages of intraday connectedness measures respond to changes in sentiment and market-specific uncertainty. Interestingly, our results contrast with earlier findings, as they show that connectedness among markets decreases in periods of high volatility owing to market-specific factors. Our study points to the importance of using high-frequency data in order to better understand market dynamics. |

| Abstract: | While experts converge on the necessity of ecological sobriety to fight climate change, our case study aims at presenting an organization intent on building a new digital ecosystem to curb and reward lowcarbon behaviours. An exploratory case study following the idea of the creation of a startup organization offers the right empirical illustration of a digital ecosystem's emergence and creation. The results indicate that leveraging digital technologies can lead to a digital ecosystem engaging organizational members toward ecological sobriety. The emergent digital ecosystem offers a new outlook on IT for Green, on innovating with disruptive technologies and on actions needed to curb carbon emissions. |

| Abstract: | Climate policies need public support to be successfully implemented as they typically come with short-term costs, whereas their revenues accrue far in the future. We study whether the occurrence of climate-related natural disasters have a systematic impact on dissatisfaction with actual environmental policies. Based on geo-referenced worldwide survey data we find robust empirical evidence in favor of the hypothesis that the experience of heatwaves, tropical storms and flood events trigger environmental policy dissatisfaction, at least when controlling for disaster severity. Thus, climate-related natural disasters, which will occur either more often or gain in severity in the course of global warming might significantly contribute to a rising public demand for more effective environmental and climate policies. However, the effect turns out to diminish over time. |
| Abstract: | Klimapolitische Maßnahmen benötigen dringend öffentliche Unterstützung, um erfolgreich umgesetzt werden zu können. Dies liegt vor allem daran, dass sie in der Regel mit kurzfristigen Kosten verbunden sind, während ihre Einnahmen weit in der Zukunft anfallen. Wir untersuchen, ob das Auftreten von klimabedingten Naturkatastrophen einen systematischen Einfluss auf die Unzufriedenheit mit der aktuellen Umweltpolitik hat. Auf der Grundlage georeferenzierter weltweiter Umfragedaten finden wir robuste empirische Belege für die Hypothese, dass die Erfahrung von Hitzewellen, tropischen Stürmen und Überschwemmungen die Unzufriedenheit mit der Umweltpolitik auslöst, zumindest wenn man für die Schwere der Katastrophe kontrolliert. Demnach könnten klimabedingte Naturkatastrophen, die im Zuge der globalen Erwärmung entweder häufiger auftreten oder an Schwere zunehmen werden, wesentlich zu einer steigenden öffentlichen Nachfrage nach einer effektiveren Umwelt- und Klimapolitik beitragen. Allerdings nimmt dieser Effekt mit der Zeit ab. |

| Abstract: | This research focuses on how quantified-self can change users' everyday urban mobility behaviour. As part of an exploratory approach, we are analysing fifty-five individual interviews of a group of young daily smartphone users. Using framing theory, our results highlight the importance of the form in which self-quantified information is presented in the context of an application with an environmental dimension. The information CO2 of individual mobility has more impact if the benefits are presented simply and in small quantities (vs. complex), in the form of gains (vs. losses), whose scope is individual (rather than collective), favouring descriptive norms (over injunctive norms), with in a short-term (vs. long-term) perspective. In the context of the ecological transition, we suggest some avenues for managerial reflection, in particular on how practitioners can design a mobile application with an environmental focus. |
| Abstract: | Cette recherche porte sur la façon dont le quantified-self peut changer le comportement quotidien de mobilité urbaine des usagers. Dans le cadre d'une démarche exploratoire, nous analysons cinquantecinq entretiens individuels d'un public de jeunes utilisateurs quotidiens de smartphones. Nos résultats soulignent, par le biais de la théorie du cadrage, l'importance de la forme de la présentation de l'information auto-quantifiée dans le cadre d'une application à dimension environnementale. L'information CO2 d'une mobilité individuelle a plus d'impact si les bénéfices sont présentés de façon simple et en faible quantité (vs complexe), sous forme de gains (vs les pertes), dont la portée est individuelle (plutôt que collective), en privilégiant les normes descriptives (aux normes injonctives), avec dans une perspective court terme (vs long terme). Dans une démarche de transition écologique, des pistes de réflexion managériales sont proposées notamment sur la manière dont les praticiens peuvent concevoir une application mobile à visée environnementale. |

| Abstract: | The range of climate change mitigation scenarios in the IPCC reports frames the futures and policies that we deem possible. In the mitigation pathways produced by Integrated Assessment Models (IAM), economic growth is sustained throughout the century, as we show by surveying the GDP trajectories considered in the IPCC AR5 scenario database and in the more recent IAM literature. We unpack the reasons for IAM's commitment to GDP growth, and seek to understand the quasi-absence of no-growth and degrowth scenarios. An overview of the current organisation of IAM research highlights the internal dynamics within the IAM community and the resulting coordination of choices. We then analyse the representation of economic growth in two IAMs, GCAM (exogenous growth) and WITCH (endogenous growth). From a technical point of view, degrowth scenarios could be considered, but the modelling teams have coordinated their work around growth scenarios. Ultimately, the absence of degrowth/no growth scenarios stems from the fact that, economic growth is largely conceived of and computed as a "natural" driver in IAM research, and not as an intervention point. |
| Abstract: | Los escenarios de mitigación del cambio climático identificados en los informes del IPCC limitan la gama de futuros y políticas consideradas. Los escenarios de mitigación producidos por los Modelos de Evaluación Integrada (IAM) suponen un crecimiento económico continuo a lo largo del siglo, lo que demostramos al revisar las trayectorias del PIB consideradas en la base de datos del Quinto Informe del IPCC y en la literatura reciente de los IAM. Analizamos las razones que podrían explicar la virtual ausencia de escenarios de no crecimiento o decrecientes en esta literatura. Con base en una descripción general de la organización actual de la investigación en torno a los IAM, destacamos el papel de la dinámica interna dentro de la comunidad IAM y las opciones de coordinación resultantes. Luego analizamos la representación del crecimiento en dos modelos: GCAM (modelo de crecimiento exógeno) y WITCH (modelo de crecimiento endógeno). Desde un punto de vista técnico, sería posible considerar escenarios de declive, pero hasta ahora los equipos de modelización han coordinado su trabajo en torno a escenarios de crecimiento. La ausencia de escenarios sin crecimiento o declive se explica principalmente por el hecho de que, en las investigaciones sobre IAM, el crecimiento económico sigue siendo considerado y calculado como un factor "natural" y no como un punto de intervención. |
| Abstract: | Les scenarios d'atténuation du changement climatiques recensés dans les rapports du GIEC contraignent l'éventail des futurs et des politiques envisagés. Les scénarios d'atténuation produits par les modèles d'évaluation intégrés (IAM) supposent un maintien de la croissance économique tout au long du siècle, ce que nous montrons en passant en revue les trajectoires de PIB considérés dans la base de données du cinquième rapport du GIEC et dans la littérature récente émanant des IAM. Nous analysons les raisons pouvant expliquer la quasi-absence de scénario sans croissance ou décroissant dans cette littérature. A partir d'un panorama de l'organisation actuelle de la recherche autour des IAMs, nous soulignons le rôle des dynamiques internes au sein de la communauté des IAM et les choix de coordination qui en résultent. Nous analysons ensuite la représentation de la croissance dans deux modèles : GCAM (modèle à croissance exogène) et WITCH (modèle à croissance endogène). D'un point de vue technique, il serait possible de considérer des scénarios de décroissance, mais les équipes de modélisation ont jusqu'à présent coordonné leur travail autour de scénarios de croissance. L'absence de scénarios sans croissance ou de décroissance s'explique essentiellement par le fait que, dans la recherche autour des IAM, la croissance économique reste considérée et calculée comme un facteur « naturel » et non comme un point d'intervention. |

| Abstract: | Design/methodology/approach This research evaluated the databases of SQL, No-SQL and graph databases to compare and contrast efficiency and performance. To perform this experiment the data were collected from multiple sources including stock price and financial news. Python is used as an interface to connect and query databases (to create database structures according to the feed file structure, to load data into tables, objects, to read data , to connect PostgreSQL, ElasticSearch, Neo4j. Purpose Modern applications of LLM (Large language model) including RAG (Retrieval Augmented Generation) with Machine Learning, deep learning, NLP (natural language processing) or Decision Analytics are computationally expensive. Finding a better option to consume less resources and time to get the result. Findings The Graph database of ESG (Environmental, Social and Governance) is comparatively better and can be considered for extended analytics to integrate ESG in business and investment. Practical implications A graph ML with a RAG architecture model can be introduced as a new framework with less computationally expensive LLM application in the equity filtering process for portfolio management. Originality/value Filtering out selective stocks out of two thousand or more listed companies in any stock exchange for active investment, consuming less resource consumption especially memory and energy to integrate artificial intelligence and ESG in business and investment. |

| Abstract: | The purpose of this paper is to critically examine the multinational oil companies (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on enhancing rural women’s financial inclusion in the areas of access to credit, insurance, propensity of the women to save and widening of economic opportunities in the Niger Delta. A total of 800 rural women were sampled across the Niger Delta region of Nigeria. Results from the use of a combined propensity score matching and logit model indicate that GMoU model made significant impact on closing the gaps in financial services, thereby removing women’s constraints on their efforts to enhancing their financial literacy. The result also confirms that, innovative delivery channels and social networks of the GMoUs have reduced some costs in the areas of access to credit, insurance, propensity to save and widening of economic opportunities to rural women in the oil host communities. However, a further look at the rural women’s participation in the CSR activities using SCOTDI, shows that even though the involvement of the women is appreciable, yet it is insignificant when compared with their male counterpart. |

| Abstract: | The public sector plays a large role in many developing economies, but its effect on earnings inequality dynamics has not been widely studied. In this paper, we investigate the earnings inequality trends and their determinants in the decades before and after the Tunisian Revolution, focusing on the impact of public wage and employment policy changes. A recentered-influence function (RIF) decomposition is performed to decompose the change in earnings into wage structure and composition effects and to assess the contribution of various determinants of inequality change. We find that earnings inequality decreased significantly during the period of investigation in Tunisia, mainly due to the decrease in the public–private wage gap and in sector wage gaps on the demand side, and the decreasing education premia on the supply side. The increase in marginal returns to average routine-task intensity jobs, the falling return to experience, and the decreasing regional wage gap also contributed to declining earnings inequality, but to a lesser extent. |

| Abstract: | The Ethiopian economy relies predominantly on rainfed agriculture for income generation, export earnings, and rural livelihoods. However, the frequency and intensity of extreme ago-climatic events projected by climate scenarios suggest considerable and growing risks from climate change to the country’s agri-food systems and the overall economy. This study assesses the economic impacts of recurrent climate shocks on the Ethiopian economy to 2040. The results indicate that recurrent climate shocks will lead to a reduction in Ethiopia's cumulative GDP from 2020 to 2040 compared to a “no climate change†baseline. Specifically, extreme weather events could cumulatively cost Ethiopia up to 17 percent (or US$ 534.3 billion) in GDP between 2020 and 2040 compared to a no-climate change baseline. The weight of the economic loss is concentrated in the agricultural production sector, with rural households and poorer households in urban areas being worst affected. Strategic investments in irrigation infrastructure and in hydroelectricity generation are found to be effective in mitigating some of the damage caused by recurrent climate variability. |
